`Speciicaton of Letters Patent. Patented Jan, 17 v1922,

Application led August 15, 1921. Serial No. 492,131.8.

To @ZZ whom` t may concern:

lle it known that I, iTwnLL J. BLACKFORD, a citizen "of the UnitedStates, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful improvements in @il HeatingStoves, of which theV following is a specification, reference being hadtherein to the Y y this cone be evenly positioned in respect to t eupper end of the wick, the flame and the spreader in order to produce aneven flame. lf this air-controlling cone is nearer to one side of thewick and the flame produced thereby, one side of the flame will burn ahigher-and smoky flame, because of imperfeet air distribution and animproper combustiongY Heretofore, this air-controlling cone has beenrigidly attached to the heating drum and it is difficult to insure theproper seating of this air-controlling cone, and it has requiredvseparate careful adjustment of each drum and cone, which adds to theexpense Y of manufacture, and in transportation the hinge of the drum,or some other part, is frequently distorted sufliciently to cause theimperfect positioning and seating of the aircontrolling cone.

The ob]` ect of my invention is to provide a construction whereby theair controlling cone is always automatically properly seated andproperly positioned without the necessity of prioradjustment and whichwill not be affected by distortions which happen in transportation oruse.

l accomplish this result by so constructing the parts Vthat vtheair-controlling cone floats within the lower end of the heating drumwith suiiicient movement independent of the drum to permit it toautomatically properly position and seat itself when the drum is turnedover the burner. v

rlhe accompanying drawing is a vertical section', showing my improvedconstruction. i Referring now to the drawing in which similar referencecharacters 'designate the same parts, 1 the fount or reservoir carryingthe usual wick tubes 2, in which the Ywick 3 `s located the usualmanner. rlhe wick tube and wick are of the annular or Argand type andsurmounted by the'usual form of perforated spreader 1l. A perforatedupwardly extending annular iiange 5 'is provided, which extends from thereservoir l andsurrounds the lower portion of the wick tubes. T his iscalled in the art a perforated Yfc-unt head. The reservoir, with theconstruction just described, is seated in a suitable perforated housing6, which is supported by suitable legs 7. A heating drum 8 surmounts theburner construction and the housing V6, the heating drum S being hingedto the housing at 9, so that it may be turned back to expose the wick tobe lighted in a' manner well underjstood by those skilled in this art. yi

The drum 8 carries at 'its lower end an inwardly and downwardly inclinedflange 1G, `whichpis referred to in'this art as the lower drum ring. l LY Theair-controlling cone ll is carried by the drum 8, so that when itis moved back for lighting purposes, theicone is carried with it. Thiscone ll surrounds the upper end of the` wick tube, thev upper end of thewick 3, and a part of the spreader 4. The

function of this cone l1 is to properly provide and direct vthe air tothe upper end of the vwick and the flame issuingtherefrom. Thisfmember'1lis necessary to produce a large flame without smoking and it isnecessary that this cone be positioned sol that it is substantiallyequi-distant from all parts of the upper end of the wick and the Haineissuing therefrom. That is to say, the cone ll mustbe so positioned thatthe wick is substantially in the center thereof, and it'is alsonecessary that the lower end l2 of the cone be properly seated on theupper end of the perforated reservoir head If this cone is not properlyseated on the perforated reservoir head 5, or if it is not properlypo-Sitioned so that the-upper end of the wick and the iiamev therefromare-substantially in the center of the cone ll, the name will be unevenand burning `higher in places, cause a smoky llame.

Heretofore, this air-controlling cone 11 has been rigidly attached tothe drum ring l() and diiiiculty has been 'experienced in causing thecone to properly seat on the reservoir 5, and properly positioned inrespect to the upper end of the wick and the become distorted intransportation by rough handling so that the cone ll does `not properly(seat and properly position. Again, the hinge vbecomes distorted in. useby careless handling with the: drum hinged backward or otherwise, thuscausing the cone to be improperly seated and improperly positionedwith'the result of uneven smoky flame.

yBy my improvement, I accomplish the automatic and certain properlyseating and positioning of the cone when the heating drum is in positionover the burner. I accomplish this by making the cone l1 a floatingmember. This is done by making the cone 11 separate from the drum ringl() and making it loose in the drum ring, so that the cone 1l haslateral and vertical movement independent of the drum Vring l0 and drum8. The diameter of the upper portion of the'cone is made suiicientlysmaller than the diameter of the opening 13 in the drum ring to permitthe cone to have lateral and vertical movement independent of the ring.The lower end 14 of the cone 11 is enlarged outward so that itautomatically properly positions itself on the upper end of thereservoir head 5, and when properly positioned on the head- 5, it isnecessarily properly positioned in respect to the upper Aend of thewick, its iiame and the spreader. V

I further provide the upper end ofthe cone ll with an outwardly enlargedand upwardly extending air deflector 15, which serves to direct outwardthe air which passes between the cone l1 and the drum ring 10, throughthe surrounding space f.

From the foregoing description, it will be readily seen that when thedrum 'is hinged backward, the cone l1 is carried with it and that after'the wick is lighted and the heating drum 8 is turned back to. operativeposition over the burner, the cone l1 automatically andcertainlyproperly seats itself on the reservoir head 5, and toV be properlyseated there is necessarily properly positioned in respect to the upperend of the Wick, its flame and the spreader 4. It will be vfurtherunderstood that this construction overcomes the necessity in manufactureof fitting and adjusting the drum, its vkhinge and the cone so that thecone properly seats and positions itself. A It will also be furtherunderstood that the Vproperly seating and positioning of this floatingcone llis not affected .by distortions of the drum, its

hinge or other parts, such as would occur in transportation or in use. Y

By this arrangementI have overcome one of the most troublesomek featuresof burners Vof this type, which has caused them to become unsatisfactoryin use, as well as to reduce the cost of manufacture.

From the foregoing description, it will be seen that the reservoir head5 co-acts with the lower end of the cone 11, to properly position it,and it is a positioning member for the floating cone.

I do not limit'niyself to the precise construction herein shown anddescribed, for this may be varied so long as itis within the scope andspirit of the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is j 1. A heater of the type described, comprising aburner, a drum surmounting the burner, an air-controlling member lhavingvertical and lateral movement independent of the drum, and a memberindependent of the drum and (Jo-acting with the lowerend of the cone toproperly seat and position the cone.
